+## Install Native Dependencies in App Directory
+
+In a monorepo, packages with native code must be installed in the native app's
+directory directly. Autolinking only scans the app's `node_modules`—it won't
+find native dependencies installed in other packages.
+
+**Incorrect (native dep in shared package only):**
+
+```
+packages/
+  ui/
+    package.json  # has react-native-reanimated
+  app/
+    package.json  # missing react-native-reanimated
+```
+
+Autolinking fails—native code not linked.
+
+**Correct (native dep in app directory):**
+
+```
+packages/
+  ui/
+    package.json  # has react-native-reanimated
+  app/
+    package.json  # also has react-native-reanimated
+```
+
+```json
+// packages/app/package.json
+{
+  "dependencies": {
+    "react-native-reanimated": "3.16.1"
+  }
+}
+```
+
+Even if the shared package uses the native dependency, the app must also list it
+for autolinking to detect and link the native code.
